The Situation<\/h2>\n\n\n\n

The Swiss Lock Anchor has been a household name in tunnel construction for more than 40 years and is specified by the Swiss Federal Office of Road Construction (ASTRA) in the Technical Manual Tunnel\/Geotechnology as a proven system for anchoring suspended tunnel decks and fire hatches, among other things.<\/p>\n<\/div>\n\n\n\n
